BBL novice Renshaw seeks more Shield runs

Matt Renshaw has admitted he needs more runs in the Sheffield Shield to confirm his place in the Australian side for the first Ashes Test in Brisbane.

The 21-year-old also revealed his desire to play all three formats for Australia after he signed his first Big Bash League contract with the Brisbane Heat.

Renshaw is confident he can balance the demands of Twenty20 cricket and still maintain his patient approach to Test cricket.

But his first priority is ensuring he retains his spot at the top of the batting order for the opener against England on November 23.

Renshaw's position is not under any immediate threat, despite national selector Mark Waugh describing his form as "patchy" after he made 17 and 16 in Queensland's emphatic Sheffield Shield win over Victoria at the weekend.

"I'm not worrying about it yet... but from a confidence point of view, you want your openers playing well," Waugh told Big Sports Breakfast.

Renshaw hasn't heard from selectors recently but said he was happy enough with his own form.
